我做了以下事情

RecordsWithIssues[,3]=tolower(RecordsWithIssues[,3])
RecordsWithIssues[1,3]

                                                                                                             OTHERCOUNTRY
                                                                                                                    <chr>

我正在尝试使用 =importxml(" http://help.sketchup.com/en/article/56085 ","/在 google 电子表格中提取http://help.sketchup.com/en/article/56085的标题/标题”）。我收到错误。

我究竟做错了什么？

谢谢

=importxml(Url,"//title/text()") 适用于除以下三个之外的大多数链接....有什么想法吗？
